There's a massive difference between the claim that "996 is the norm" and the reality that this was largely restricted to large tech companies, is acknowledged as a real problem by the government, and that said government has taken concrete steps towards eliminating this entirely. Of course, reality is not black and white, just because something is formally illegal does not mean that it has been eliminated entirely, but this is a universe apart from the claim that "996 is the norm."

Regarding the question of whether trade unions should be independent or incorporated and federated, historical practice proves the necessity of unity over fragmentation. The Jasic incident actually demonstrates this quite well, as western organizations such as BBC, Amnesty International, and Radio Free Asia got involved in the incident and tried to spin it. Preventing western influence over soveriegn structures is critical to the longevity of the socialist peoject, and the fact that unions must work within the existing socialist system is miles apart from the claim that "unions are illegal."

As for students discarding what of Marxism they learn, this isn't unexpected. No socialist country can manage to make all students interested in Marxism. Your claim, however, made it appear that Marxism itself is discouraged. Regarding the Peking University Marxist Society, the students had this to say:

As one of the students told The Washington Post, they believe "Once you study Marxism, you know real socialism and China's so-called socialism with Chinese characteristics are two different things. They sell fascism as socialism as a street vendor passes off dog meat as lamb."

This is not Marxist analysis, this is left-dogmatism. In the PRC, public ownership is the principle aspect of the economy, and the working classes have political control of the state, not capitalists. The accusation of fascism is coated in Marxist analysis, but is ultimately left-deviationism and counter-revolutionary. Their accusation is ironic, and just like the Jasic incident, it is the exact type of fragmentation that undermines socialist construction through left phrasemongering and coating.

The claim that western orgs are reluctant to cover China's working conditions is utter fantasy. In the west, we are drilled with propaganda about conditions in China daily. There is a real information war against China waged daily in the west. I'm aware that China is rife with contradictions, such is the result of a rapidly developing country trying to navigate ongoing class warfare, urban/rural mismatched development, problems arising from the existence of liberals and capitalists in China empowered by Reform and Opening Up, and more. However, the PRC is constantly and regularly improving, the state enjoys approval rates exceding 90%, and the CPC is regularly addressing the real issues in China.

Overall, your framing is highly deceptive. Rather than discussing real problems honestly, you try to hide their context, complexity, and nuance. This isn't a Marxist method of problem solving and discussion, there's no adherance to unity-struggle-unity. A discussion base built on deception is pointless, theory and practice must be united to be accurate and effective.
